Uterine polyps are common, non-cancerous growths that develop on the inner lining of the uterus, known as the endometrium. These growths can cause symptoms like abnormal bleeding between periods or heavy menstrual flow. The standard treatment involves a minimally invasive procedure called a hysteroscopic polypectomy, where a thin, lighted instrument is used to remove the polyp from the uterine cavity. Many people wonder when their regular menstrual cycle will resume, as the body adjusts to the tissue removal and the healing of the uterine lining.
Differentiating Post-Operative Spotting from Menstruation
The bleeding experienced immediately following polyp removal is not a period but a normal part of the healing process. This post-operative discharge is typically light spotting, appearing as a watery pink or brown fluid, or a small amount of bleeding. This occurs because the procedure creates a small wound where the polyp was attached to the uterine wall.
This spotting is expected and generally subsides within a few days, although some people may notice it intermittently for up to two weeks. The flow should be significantly lighter than a typical menstrual period, indicating the body is repairing the endometrial surface. If the discharge is heavy, persistent, or requires frequent pad changes, it should be addressed by a healthcare provider.
The Typical Timeline for Your First True Period
For most people, the first period after a hysteroscopic polypectomy will arrive approximately four to six weeks following the procedure. This timeline aligns with the natural cycle of endometrial regeneration and shedding. The procedure itself does not typically reset the hormonal cycle that governs menstruation, but it does cause a temporary disruption in the uterine lining.
The timing of the next period is influenced by when the surgery occurred relative to the patient’s existing cycle. If the removal was performed just after a prior period, the body has a longer time to complete the follicular phase, meaning the next period will arrive closer to the six-week mark. Conversely, if the procedure happened close to the expected date, the cycle might be shortened, and the period could arrive sooner, perhaps within two or three weeks. The characteristics of this first cycle may also differ, sometimes presenting as slightly heavier or lighter than usual as the uterus adjusts to its renewed state.
Individual Factors That Influence Cycle Return
Several personal factors can extend or alter the four-to-six-week timeline. One significant variable is the patient’s cycle regularity before the surgery; individuals who previously had irregular periods may find their post-operative return to be unpredictable. The underlying hormonal balance that dictates the menstrual cycle can take time to stabilize.
The complexity of the polypectomy procedure also plays a role in the healing duration. Removal of multiple or very large polyps requires more extensive manipulation of the uterine lining, which can necessitate a longer recovery time before the endometrium is ready for a full menstrual shed. Furthermore, psychological and physiological stress resulting from the surgical experience can temporarily suppress the hormonal signals necessary for timely menstruation. Patients using hormonal contraceptives may experience a predictable return or withdrawal bleed based on their pill schedule, as these medications often override the natural cycle.
Recognizing Signs That Require Medical Attention
Although minor discomfort and spotting are normal, certain signs indicate that a complication may be occurring and warrant immediate medical contact. One concerning sign is the complete absence of a period more than eight weeks after the procedure, which should prompt a call to your doctor for evaluation. A delay beyond the expected window may simply be due to healing or stress, but a prolonged absence needs to be investigated.
Heavy bleeding is another serious symptom, defined as soaking through more than two full-sized sanitary pads in one hour for two consecutive hours. Severe or worsening pelvic pain that is not relieved by over-the-counter pain medication is a sign that should not be ignored. Signs of infection, such as a fever greater than 100.4 degrees Fahrenheit, or a vaginal discharge that has a foul or unusual odor, also require prompt medical attention.
